If you are on a tight budget, these aftermarket twin-leading-shoe wheel cylinders are ideal. This is the left side, 15/16" bore as used on later models. Sold each, use two (2) per car. See GWC0127 for Lockheed.
If using these wheel cylinders to upgrade earlier .80" bore twin-leading-shoe wheel cylinders for better braking, please use late brake backing plate 37H2014, which has manufacturer number of 4461-733 stamped inside.
